What does brass mean

The alloy of copper and zinc is called brass!

Brass consisting of copper and zinc is called common brass.

If it is made up of more than two elements, it is called special brass. Such as copper alloy composed of lead, tin, manganese, nickel, iron and silicon. Brass has strong wear resistance. Special brass is also called special brass, which has high strength, high hardness and strong chemical resistance. The mechanical properties of cutting are also prominent. The seamless copper tube made of brass is soft and wear-resistant. Brass seamless tubes can be used in heat exchangers and condensers, low temperature pipes, and submarine transport pipes. Manufacture sheet material, bar material, pipe material, casting parts and so on. Copper in 62% ~ 68%, strong plasticity, manufacturing pressure equipment. According to the different kinds of alloying elements contained in brass, brass can be divided into ordinary brass and special brass. The brass used in pressure processing is called deformed brass. Brass is a copper alloy with zinc as the main additive element. It has a beautiful yellow color. Copper zinc binary alloy is called common brass or simple brass. Brass above three yuan is called special brass or complex brass. Zinc less than 36% of the brass alloy composed of solid solution, with good cold working performance, such as zinc 30% brass commonly used to make shell cases, commonly known as the bullet

Shell brass or 730 brass. Brass alloys with zinc content between 36 and 42% are composed of and solid solutions, of which the most commonly used is 64 brass with zinc content of 40%. In order to improve the performance of ordinary brass, other elements such as aluminum, nickel, manganese, tin, silicon and lead are often added. Aluminum can improve the strength, hardness and corrosion resistance of brass, but reduce the plasticity, so it is suitable to be used as condensing pipe and other corrosion resistant parts. Tin can improve the strength of brass and corrosion resistance to seawater, so it is called naval brass, used for Marine thermal equipment and propellers. Lead can improve the cutting performance of brass; This free - cutting brass is often used for clock parts. Brass castings are commonly used to make valves and pipe fittings.
